8 Things You Can Do To Reduce Light Pollution

Until I interviewed the Dark Ranger (aka Kevin Poe), I hadn’t thought much about the seeming disappearance of the stars in the sky. I knew my suburban existence had something to do with not seeing as many stars as I remember as a kid, but I also figured I had romanticized that magical sparkly starry sky of my summer-camp days in the Berkshire mountains of Western Massachusetts. The other time I remember a fabulously star-filled sky was during a honeymoon trip to a pretty remote island – the tiki torches didn’t seem to diminish the twinkling of that night sky much at all.

Kevin (who I kept calling Ken during our first interview – Sorry Ken, I mean Kevin! Public apology #2), is a park ranger in Mt. Zion National Park and has made it somewhat of a life’s mission to help illuminate (cute, right?) us about why we need to start paying attention to light pollution.

Waste of Energy – Let’s face it, there is probably a lot of over-illuminating going on, especially here in the US, where we have an obsession with keeping the lights on all night. According to the International Dark Sky Association, we burn up a whopping 22,000 gigawatt-hours of useless light that is pointed up towards the sky! Their math has this at an estimated cost (in terms of money) of $2.2 billion a year. In terms of carbon footprint?

3.6 million tons of coal or 12.9 million barrels of oil is used

Ecosystems & Wildlife – While light pollution can disrupt elements of the ecosystem in subtle ways that may ultimately have lasting effects, it has a definite and negative impact on nocturnal animals. In general all animals (including humans) have a biological code that follows a circadian rhythm, which is just a inherent natural clock.
